The factors of the quadratic equation are (x+3) and (x-15).
<h2 /><h2>Given to us</h2>The factors of .
As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².
therefore, dividing -12x into -15x and 3x,
Taking common out,
Hence, the factors of the quadratic equation are (x+3) and (x-15).
